did you just solder the 1st fet drain to source?

Just trawling my old laptop diagnosing posts and seen added posts since original board view request..i lost interest in the board after a couple of months of unsuccessful attempts.

one day i may dig out the L560 board and try the sw 1 top pins bridge only suggestion by rbvdon..

board won't be worth much even if fixed, but hey, sometimes its about the challenge.

smd Flea, thanks for comment regarding mosfet bypass, At the time I watching to many early you tube videos (Sorin) showing mosfet bridging as a solution.

I now understand the dangers of inducing a false start scenario.
